Triple-hulled vessel

Abstract

The invention discloses a triple-hulled vessel. The triple-hulled vessel comprises a triple-hulled vessel form, a water wing system and a spoiler system, wherein the triple-hulled vessel form is formed by a main hull and a two side hulls; the water wing system consists of a front water wing, a middle water wing and a rear water wing; a spoiler is mounted at the bottom of the tail end surface of the main hull; the longitudinal motion of the spoiler on the tail end surface of the main hull is realized by using a spoiler controller; and the height, extending out of the bottom of the tail end surface of the main hull, of the spoiler is controlled by using the spoiler controller. According to the triple-hulled vessel, through the coordination between the water wing system and the height adjustable spoiler, a longitudinal self-stabilizing moment is generated to balance the longitudinal swinging moment which is generated by the triple-hulled vessel during sailing at a high speed; and therefore, the longitudinal stability of the triple-hulled vessel is greatly enhanced.

Description

technical field [0001] The invention relates to a trimaran and belongs to the technical field of composite high-performance ships. Background technique [0002] High-speed ships with a displacement of 100-600 tons and a design speed of 40-50 knots are widely used in both military and civilian applications due to their high speed and low overall cost. This type of high-speed ship is a ship type between a displacement ship and a planing boat, called a transitional ship type. In order to meet the requirements of lateral stability, the conventional monohull hull generally has a small length-to-width ratio, so the wave-making resistance and wave-increasing resistance in wind and waves are relatively large, and the economy and safety in the transition stage are poor. The trimaran type just appeared to solve the limitations of the monohull type at high speed. [0003] The main hull of the trimaran has a large length-to-width ratio, which is a slender body structure, and the lengt...

AI Technical Summary

Problems solved by technology

[0003] The main hull of the trimaran has a large length-to-width ratio, which is a slender body structure, and the length-to-width ratio is generally more than 10. The front part of the main hull is designed as a pointed cone, and its wave resistance and wave resistance are small, but the lateral stability insufficient

Due to the changing conditions of the ship during navigation, the fixed hydrofoil is less adaptable

The hydrofoil with variable angle of attack can solve such problems. The automatic control system continuously adjusts its angle of attack according to sea surface conditions, hull attitude, speed, acceleration and other parameters to obtain different dynamic lift. However, this structure is relatively complicated. High processing cost

These patents do not mention how to improve longitudinal stability
